Cannibal Cards is a classic plot in card magic developed by Lin Searles, marketed in 1959, where cards disappear when sandwiched between other cards (that is, they are "eaten" by the "cannibal" cards.) The original routine uses gimmicked cards, which eat various small objects (such as a paper clip) in addition to other cards.

Later, magicians began developing sleight of hand versions. The prototypical version first published with credit to Matt Corin in Kabbala #1 (1971).

In a footnote within The Legendary Kabbala (1998), Racherbaumer cites that Corin learned this routine from Sam Schwartz, who at the time had not yet published it. Fulves eventually published it as "A.E.-I.O.U" in Epilogue #14 (March - 1972). Corin demonstrated it to Racherbaumer during the I.B.M. Convention in 1971 and it was subsequently published in Kabbala.

Wesley James, however, claims that he demonstrated his creation to Matt Corin before it was published in Kabballa. (See James' "The Magical Record and Thoughts" or Epilogue Special No. 4 )
